Beschreibung
Zusammenfassung:	An electronic device connection unit includes a substrate and a plurality of signal pads on the substrate configured to send signals from an electronic device to a driving printed circuit board (PCB). One or more active ground pads on the substrate are configured to connect at least the driving PCB to a reference voltage of the electronic device. One or more dummy ground pads on the substrate are configured to connect to the reference voltage of the electronic device without extending onto the driving PCB. One or more connectors are connected to the one or more dummy ground pads, where each of the one or more connectors is configured to electrically couple at least a subset of the one or more dummy ground pads to the one or more active ground pads.
